I have an actyvity_main, containing 3 radiobuttons (each one corresponds to a layout), and a button. After the user selects the option, he clicks the button, which makes a call to another activity, where in it, I need to do with the selected layout.

public void onClick(View view) {
        int checkeRadioButtonId = escolhaRadio.getCheckedRadioButtonId();
        switch (checkeRadioButtonId) {
            case R.id.rdb1:
                Intent opcao8 = new Intent(this, Activity_Jogo.class);
                setContentView(R.layout.layout_8);
                startActivity(opcao8);
                break;
            case R.id.rdb2:
                Intent opcao10 = new Intent(this, Activity_Jogo.class);
                setContentView(R.layout.layout_10);
                startActivity(opcao10);
                break;
            case R.id.rdb3:
                Intent opcao12 = new Intent(this, Activity_Jogo.class);
                setContentView(R.layout.layout_12);
                startActivity(opcao12);
        }
    }

In this way I'm doing it, it calls the layout and, after appearing it instantly calls the activity, leaving only the activity with its default layout.

The simplest way would be to pass the resource from layout to Extras , and recover at next Activity :

public void onClick(View view) {
    int checkeRadioButtonId = escolhaRadio.getCheckedRadioButtonId();
    Intent i = new Intent(this, Activity_Jogo.class);

    switch (checkeRadioButtonId) {
        case R.id.rdb1:
            opcao10.putExtra("opcao", R.layout.layout_8);
            break;
        case R.id.rdb2:
            opcao10.putExtra("opcao", R.layout.layout_10);
            break;
        case R.id.rdb3:
            opcao10.putExtra("opcao", R.layout.layout_12);
            break;
    }

    startActivity(i);
}

In the onCreate method of your Activity_Jogo you would retrieve this value and use it as contentView :

@Override
protected onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    int layout = getIntent().getIntExtra("opcao", 0);

    // Se ninguem passou um layout como parametro,
    // voce pode usar um padrao ou fechar a Activity
    if(layout == 0) {
        finish();
    }

    setContentView(layout);

    // Restante do seu processamento...
}
